[Agda] Unreadable constraints, problem with name printing?

What does this constraint mean?

  (_138 {.X} {.R} {.S} R⊆S step x {_} {_}
    {_139 {.X} {.R} {.S} R⊆S step x {_} {_}}
    {_140 {.X} {.R} {.S} R⊆S step x {_} {_}}) = _ : .X

I am puzzled about the _ on the r.h.s., and also in the implicit 
arguments to the meta.

Is this supposed to be a variable name?  Are all _ the same variable?
